Herein, the synthesis and characterization of an alkyne‐modified luciferin is reported. This bioluminescent probe was accessed using C−H activation methodology and was found to be stable in solution and capable of light production with firefly luciferase. The luciferin analogue was also cell permeant and emitted more redshifted light than d‐luciferin, the native luciferase substrate. Based on these
本文报道了炔烃修饰的萤光素的合成和表征。使用CH活化方法可访问此生物发光探针,发现该溶液在溶液中稳定并且能够通过萤火虫荧光素酶发光。萤光素类似物也能渗透细胞,并且比天然萤光素酶底物d luciferin发出更多的红移光。基于这些特征,炔基荧光素可用于多种成像应用。
